The International Code Council and Calidad and Sustentabilidad en la Edificacion A.C. have announced the publication of the Mexico Conservation Code for Buildings—the first model energy code in Mexico. Mexico’s National Commission for Energy Efficiency is working with local authorities to select municipalities to get the code adopted and implemented. The code, based on the ICC’s model International Energy Conservation Code, establishes minimum requirements for building energy use and allows for the use of prescriptive and performance-based approaches. It also permits use of new energy-efficient designs and materials. The code applies to non-residential buildings, including mixed occupancies, and residential buildings up to three stories.
